摘要：Disclosed is a novel process for the preparation and separation of
cyclopropanecarbonitrile (CPCN) from cyclopropropanecarboxaldehyde (CPCA) using acombination of three process steps. The process involves the steps of (1) reacting (CPCA)with hydroxylamine base in the presence of water to obtain CPCA oxime, (2) contactingthe CPCA oxime of step (1) with formic acid to obtain CPCN, and (3) contacting themixture comprising CPCN formed in step (2) with a base to obtain a mixture comprising anorganic phase containing CPCN and an aqueous phase. The reactants and intermediatesinvolved in each step are used within certain defined ratios.
